Abstract (en)
[origin: EP2305423A1] The method involves correcting shape of a projected longitudinal profile (52) so as to equalize perimeter length of the profile with perimeter length of an acquired longitudinal profile (50). A trimming instruction is deducted from a corrected longitudinal profile (53). The correction step is performed by stretching the longitudinal profile according to a given mathematical function, the projected profile along an ordinate axis (Y2) transverse to a horizontal axis (X2) and by compressing the stretched longitudinal profile along the horizontal axis orthogonal to the ordinate axis.
